Jewels

Jewels are socketable modifiers that change how a spell behaves, adding effects like extra projectiles, longer stuns, more lifesteal, or reduced cooldowns. You find them as drops and craft or refine them at a Jewelcrafting Table, then slot a Jewel into a matching spell to tune it for your build. Hunting the right Jewel for your favourite spell is a big part of late-game optimization. Higher-tier Jewels roll stronger and rarer modifiers.
